    Just had my 98 seat arosa in for NCT and failed due to emissions. Readings were

    lambda...... 1.04 (not between .97 and 1.03)
    CO........ 0.47 (above .30%)
    HC....... 324ppm (above 200ppm)

    This was on retest and between tests i had fitted a whole new exhuast system complete with catalytic converter.

    Does anyone know what these readings mean and how i might fix the problem.
